.MFITKOD OF SEWING POWDER PUFFS.

Application filed September 21, 1922. Serial No. 589,555.

a s ecificat on 10 y invention relates to a new and improved method for the sewing of powder puffs.

One of the objects of my invention is to provide a new and useful method which shall be capable of use with the large automatic machines shown in my copending applications Serial No. 539,101 filed February 25th, 1922, and Serial No. 463,018 filed April th,.1921.

I have found that it is desirable and neoemary in order to secure uniform production, to compact the material from which the puffs are manufactured, namely lambs wool or the like, at the edges thereof and while the said material is being sewed together. I have also found it highly desirahle to push the edges of the nap of said material inwardly while the said sewing operation is being performed. These additional operations cause the edge of the completed putt to have a neat and finished ap earance.

ther objects of my invention will be set forth in the following description and drawings which illustrate a mechanism suitable for practicing my method.

Fig. 1 is a side elevation of a mechanism suitable for practicing my method.

Fig. 2 is a section on the line 22 of Fig.1.

Fig. 3 is an enlarged view in elevation partially in section.

Fig. 1 is a section on the line H of Fig. 1.

Fig. 5 is a section on the line 5-5 of Fig. 3; f

Fig. 6 is an enlarged sectional view of one of "the holding and compacting fingers.

Two discs of fabric D are out by any suitablemeans and placed one on top of the other with the sides having the naps thereon adjacent each other as clearly illustrated in Figs. 1 and 3.

' These superposed discs D are preferably In making powder puffs from lambs wool I .2, the end of the pusher bar by means of screws 17 held upon needles 1- mounted upon the revoluble carrier disc 2, which is carried ,by the holder 3, but they may be held by any suitable means. I have not illustrated the automatic mechanism for cutting out the discs D and placing them upon the needles 1 because this is thoroughly setforth in my copending application filed February 25th, 1922, and this could be done by hand, if desired.

The edges of the discs I) are sowed together by any suitable sewing machine. of which a conventional type is illustrated in thedrawings. For a brief description of the said Sewing machine, 1 may state that .this has the rocker arm 2 pivoted at 3 to the frame 4 and that the needle N is socured to the ordinary needle bar The presser foot P, feed dog, etc., of the scuing machine may be of any suitable type. The sewing machine is driven by any ordinary belt 6 which passes around any ordi nary pulley 7 mounted uponthe'shaft 8. -The machine is provided with the ordinary tension means 8' and stitch regulating means 9 and a stopping device 10 which are suiiicicntly described in my saidapplication Serial No. 539,101 and in themselves form no part of my present invention. 4

. While the revoluble holding disc 2 is being revolved, and while the sewing operation is being performed the nap terial of which the discs D are formed is continuously pushed inwardly by a pushor 11. For this purpose the the cam 12 provided with a cam groove into-which fits the roller 14-. connected to the pusher 11. As clearly shown in Fig. 11 is provided with a series of teeth '15 so as to more efliciently operate upon the loose fitifly material with which it contacts. The pusher bar 11 is mounted in guides in the frame 161 The frame 16 is mounted in the main machine frame 1 by means of screws 17. The plate 18 is connected to the frame 16 and 19 and this plate 18 has two holding bars or lingers 20 and 21 pivoted upon the screws 19. These holding bars 20 and 21 are pivoted so that they can be oscillated in the vertical p ane and their fiat ends are provided with a series of teeth 22 as clearly shown in Fig. 6. The pusher bar is provided with two of the mashaft 8 has and 21 so that the movement of theisaid -pusher bar 11 to the left of the position shown in l1 in. 3 tends to move the teeth Q2 of the said holding bars 20 and 21 towards each other. The holding bars 20 and 21 are normally separated by the expansion spring 24. l

The operation of my device is as follows:

The holding discs are continuously royolved while the needle bar is coutinuoiuly reeipro :ated in the well known manner. The holding bars 20 grip and hold and compress the fabric just before the needle penetrates the fabric so that the fabric can not buckle or more b cause of the'action of the pusher bar 11 which operates to push the soft fluffy material of the nap of each disc inwardly just. before the needle penetrates the fabric to form the stitch.

Hence during the sewing operation the two discs of fabric are compressed and the nap of the material at the periphery thereof is forced inwardly. The holding bars 20 and 21 are moved in opposite directions to release the fabric and the pusher bar 11 is also moved outwardly to release the fabric just. before the needle N is moved upwardly to release the fabric. Hence the first oporation upon the fabric is to grip it between the holding bars. The next operation is to inwardly push the nap of the fabric. The next operation is the beginning'of the formation of the stitch. by the downward movement of the needle. Then the pusher bar 11 is moved in a direction away from the needle, the holding bars are opened by the compression spring 24: and the needle end leaves the fabric with the stitch completely formed.

The member 11 may at all times project somewhat between the discs D so that as the said discs are continuously revolved "the nap- I have shown a preferred embodiment of my invention but it is clear that numerous changes and omissions can be made without di-iparting from its spirit and where I refer to the parts herein either in the description or the claims by means of numerals, I do not wish to be limited to the specific embodiment herein disclosed.

I claim 1. A method of sewing a powder pulf which consists in sewing together corresponding portions of two discs of fabric of which said putt is composed and each of which has a base and a nap surface While said nap surfaces are facing each other, while inwardly pushing the naps-of said discs as the stitches are formed so that said the upright nap stitches do not encircle fibres, then turning the bag-lilte article formed by sewingtogether the said corre-. sponding portions of said discs until the bases of said discs face each other and then connecting the unsewed portions of said discs. Y i

2. A method according-to claim 1 in which the edges of said discs are heldjand The sewing pressed together durirnc the sewing together of said corresponding disc portions. L

In testimony whereof I hereunto affix my signature.
